The Green River Ordnance Plant, also known as the Green River Arsenal, was a large munitions factory complex between Dixon and Amboy in Lee County, Illinois. Constructed in 1942 and then shut down in 1945, it produced rocket-propelled bazooka ammunition, artillery shells, naval shells, bombs, rifle grenades, fuses and rockets for use during World War II.
Access to the plant was granted by two different railroads, each via their own line, now both abandoned: the Chicago, Burlington & Quincy and the Illinois Central.
